问题:
I am using the Tcpdf module and PHP to create dymanic PDF invoices from an ordering system.
The script should then save the invoice into a folder called "invoices". The folder exists, and there are full permissions for "everyone" (Windows).
The code I am using is this:
$pdf->Output('invoices/Delivery Note.pdf', 'F');
This uses fopen to save the file.
However the error I am getting is: Warning: fopen(): remote host file access not supported, file://invoices/Delivery Note.pdf
This is a local file, not a remote one.
I attempted adding a / prefix like this:
$pdf->Output('/invoices/Delivery Note.pdf', 'F');
but then I get this error instead: Warning: fopen(file:///invoices/Delivery Note.pdf): failed to open stream: No such file or directory
I created the file, and left it empty, but the same error as above.
Does anyone know why I am getting this error?
回答1:
From php-Script you can use:
$pdf->Output(__DIR__ . '/invoices/Delivery Note.pdf', 'F');

After upgrading to the tcpdf 6.2.6 in vtiger 6.2 I've had the same problem, sending e-mail with pdf.
So I have changed the file:
libraries/tcpdf/include/tcpdf_static.php
I have commented the code in fopenLocal() and changed the line
fopen($_SERVER['DOCUMENT_ROOT'].$filename, $mode);
see:
/** * Wrapper to use fopen only with local files * @param filename (string) Name of the file to open * @param $mode (string) * @return Returns a file pointer resource on success, or FALSE on error. * @public static */ public static function fopenLocal($filename, $mode) { // if (strpos($filename, '://') === false) { // $filename = 'file://'.$filename; // } elseif (strpos($filename, 'file://') !== 0) { // return false; // } return fopen($_SERVER['DOCUMENT_ROOT'].$filename, $mode); }
After changing this, it worked.

similar to user1007017
, but just comment the line like shown below (tcpdf 6.2.11)
public static function fopenLocal($filename, $mode) { if (strpos($filename, '://') === false) { //$filename = 'file://'.$filename; } elseif (stream_is_local($filename) !== true) { return false; } return fopen($filename, $mode); }

I found the issue was that the path for fopen has to be from the document root, and not from the PHP script location.
C:\Website\www\script\invoice\invoice.pdf
For example if the PHP script is inside the "script" folder, and you want to create the pdf inside the "invoice" folder, the script needs to have "\script\invoice\invoice.pdf".

I suggest using the following as Gerd has also suggested but make sure you use an absolute path:
$pdf->Output(__DIR__ . '/invoices/Delivery Note.pdf', 'F');
The path must be an absolute path & not a relative path. This PHP bug report explains why: https://bugs.php.net/bug.php?id=28820
The reason relative paths are not supported with the file:// wrapper comes down to a compromise in how UNC paths are dealt with (and more specifically how / are fuzzily interpreted as \ for windows installations).
For Example:
file://foo/bar
Could be interpreted as a relative URI: foo/bar from the current working directory, OR it could be interpreted as a UNC: \foo\bar (share bar
on computer foo
).
For this and a few internal reasons the file:// wrapper is limited to absolute paths when called explicitly. For relative paths either use realpath() {as you did in your report}, or omit the explicit naming of the file wrapper.
You can then avoid modifying the TCPDF code and worrying about any upgrades replacing your modified code.

try this
$pdf->Output($_SERVER['DOCUMENT_ROOT'].'/invoices/Delivery Note.pdf', 'F');
